Hi I have OSX Server running on a mac mini with a few shared volumes. This setup has been running fine for years. I am adding a ned disk. Everything issuing fine until I get to the point to add users to the disk (in the server app under file sharing ) I will add the users bit when I hit save a get a error "Failed to save access control list" "Make sure access control list are enabled on the volume"
I not sure what to do next
